Should we (the people) should be given a very clear definition of “broken” and “comprehensive reform”.?

We hear the words “comprehensive immigration reform” and “broken immigration system” . I do not recall ever reading or hearing, exactly what, or how,it is “broken”. The existing system apparently worked well enough to LEGALLY admit millions (by quota) prior to the runaway ILLEGAL entry problem. Do you think we (the people) should be given a very clear definition of “broken” and “comprehensive reform”. ?
